Hi ZY,
The Camera app is distributed through the Microsoft Store, which normally requires an online connection. However, for offline scenarios, you can download the offline installer package (Appx or MSIX) from the Microsoft Store for Business or from the Microsoft Update Catalog on another machine that has internet access. Once downloaded, you can copy the package to your offline PC and install it manually.
To do this, you’ll need to use PowerShell with the Add-AppxPackage command to install the Camera app from the offline package. Make sure you also download any dependency frameworks (like Visual C++ runtime or .NET components) that the app requires, otherwise the installation may fail. If your environment uses Microsoft 365 management center, you can also export the app package from there for offline deployment.
It’s important to note that updates for the Camera app will not apply automatically without internet access. You’ll need to repeat the process periodically by downloading the latest package on a connected machine and transferring it over.
